摘要:
A liquid crystal composition and a liquid crystal display including the liquid crystal composition that includes a first class containing a fluorine-containing liquid crystal compound represented by Formula I (n=1, 2, or 3), and a second class containing at least one neutral liquid crystal compound represented by Formulae III, IV, and V. In Formula I, W1 and W2 are each independently selected from the group consisting of —F, —CF3, —CF2H, —OCF3, and —OCF2H, the liquid crystal compounds represented by Formulae I, III, IV, and V have R1, R2, and R5 to R10 that are any one of a hydrogen atom, and an alkyl group, an alkoxy group, and an alkenyl group having 1 to 12 carbon atoms as terminal groups, and a first sub-class has a content of 6 wt % or less based on a total content of the first class and the second class, with the proviso that a liquid crystal compound of the first class having n=1 is the first sub-class and a liquid crystal compound of the first class having n=2 or 3 is a second sub-class.
摘要:
The present invention discloses a liquid crystal composition having a first class compound including a fluorine-containing compound, and a second class compound including a neutral liquid crystal compound, where each terminal group of the neutral crystal compound includes an alkyl group, an alkoxy group, or an alkenyl group. If the neutral liquid crystal compound includes an alkenyl group at the terminal group, the liquid crystal composition includes less than 7 wt % of the neutral crystal compound including the alkenyl group. The present invention also discloses a liquid crystal display including the aforementioned liquid crystal composition.

摘要:
Disclosed is a liquid crystal display that includes a first substrate, a second substrate facing the first substrate, a pair of field generating electrodes formed on at least one of the first substrate and the second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate. The liquid crystal layer comprises a liquid crystal composition that includes a first class having at least one fluorine atom, and a second class containing a neutral compound. The second class includes a first sub-class and a second sub-class. The first sub-class contains a liquid crystal compound having at least one selected from an alkyl group and an alkoxy group having C1 to C5 in a terminal group thereof. The second sub-class contains a liquid crystal compound having an alkenyl group having C1 to C5 in terminal groups thereof. The second sub-class is contained in a content of about 7 wt % or less of a total content of the liquid crystal composition.

摘要:
A liquid crystal display (LCD) device includes a backlight assembly, a contrast ratio increasing LCD panel and an image displaying LCD panel. The contrast ratio increasing LCD panel is disposed on the backlight assembly to increase a contrast ratio. The image displaying LCD panel is disposed on the contrast ratio increasing LCD panel to display an image. Thus, the LCD device may have a high contrast ratio by increasing a contrast ratio between the luminance of a black color and the luminance of a white color.
